[#8890] ServiceLoader does not work properly in OpenJ9

[smilu97]

In OpenJ9 JDK11, All modules are forced to have System.bootLayer as their layer when they are defined by java.lang.Access::defineModule source. This difference between HotSpot and OpenJ9 is currently disrupting java.util.ServiceLoader finding service providers in OpenJ9.

This problem can be resolved by binding Java9ClassLoader to System.bootLayer manually, but I'm not sure this is a good idea.
